DRAIN CONNECTION Application filed February 20, 1928.

I lhis invention relates to an improvement in drain fittings especiallydesigned and adapted for use with all metal shower stalls, although alsoadapted for advantageous use with various types of tanks, tubs, basins,or other receptacles.

Metal shower stalls and other receptacles of a similar nature having anoutlet opening through which the water or the like drains 10 and theproper connection of this outlet opening to a drain pipe or olitake pipehas presented a problem that is a source of considerable ditliculty,annoyance and expense. It has been proposed to secure a drain fitting tothe stall or other receptacle around the outlet opening,the drainfitting being of annular form and being threadedly connected orotherwise appropriately secured to the oil'- take pipe or to a couplingmember connected 2 to such a pipe. With this construction, however,water finds its way into the interstice between the annular body of thedrain fitting and the adjacent portion of the shower stall and sets upcorrosion which breaks down the structure of the shower stall around thedrain opening. As these shower stalls are built into the structure ofthe building in which they are provided itis impossible to get to thedrain fitting unless the stall is torn out of the building.

One of the principal objects of the present invention is to provide adrain fitting which is so organized with the shower stall as to precludeany possibility of a shower stall becoming corroded or broken downaround the drain opening.

Another object is to provide a device of this character and having theseadvantages and capacities and which is of simple and dur- 46 ableconstruction, reliable and efiective in operation and easy andcomparatively ineXpensive to manufacture and apply.

In carrying out the present invention a drain fitting is provided whichconsists of an annular body fitted flush up against the underside ot theshower stall or the like around the outlet thereof.j A weld is providedbetween the periphery of the annular body and the underside of theshower stall which se- 50 cures the drain fitting to the shower stalland Serial No. 255,717.

closes the interstice between the shower stall and the drain fittingaround the outer periphery of the drain fitting. In addition, means isprovided for sealing the interstice between the drain fitting and theshower I stall all around the entrance to this interstice located at themarginal wall of the outlet opening. This sealing meansmay consist of aweld between the marginal wall of the outlet opening and the drainfitting or it may take any other appropriate form.

Other objects and advantages reside in certain novel features of theconstruction, arrangement and combinationof parts which willbehereinafter more fully described and particularly pointed out in theappended claims, reference being had to v the accompanyingdrawingforming a part of this specification, and in which:

The figure is a fragmentary sectional View 76 showing'a fragment of areceptacle such as a shower stall, tank, basin, tub, or the like,equipped with a drain fitting embodying the present invention.

Referring to the drawing, the numeral 1 designates a portion of thebottom of a show er stall, or the like, and, as shown, it is formed withan outlet or discharge opening 2. A drain fitting is provided for theopening 2 and comprises an annular body 3 having an so outwardlydirected peripheral flange 4. The drain fitting is fitted flushupagainst the tin derside of the bottom of the shower stall and has aportion lapping the outlet opening and a portion lapping the structureof the shower s5 stall around the outlet opening. Between the peripheryof the flange l and the adjacent structure of the shower stall a weld 5is provided, this weld 5 extending entirely around the circumference ofthe flange 4t and serving to secure the fitting to the shower stall andto close the space or interstice between the drain fitting and theshower stall around the outer periphery of the drain fit ting.

An annular groove 6 of V-shape in cross section is provided in the drainfitting and partially underlies the bottom of the shower stall andpartially underlies the outlet opening 2 formed therein. In this groove6 means is provided for sealing the interstice or space between thedrain fitting and the shower stall around the margin of the outletopening. This means may consist of a weld 7 filling the groove 6 anduniting the structure of the drain fitting to the marginal portion ofthe outlet opening 2 or it may consist of a filling of cement in thegroove 6 which also secures or welds the drain fitting to the showerstall structure and seals the interstice between the drain fitting andthe shower stall around the entire margin of the outlet opening. By thuscompletely sealing the interstice between the drain fitting and theshower stall any ingress or accumulation of moisture in the intersticeor crevice between the fitting and the receptacle is prevented and allpossibility of corrosion of the shower stall or other reccotacle isprecluded. Moreover, the structure of the shower stall or otherreceptacle around the outlet opening is strengthened and reinforced.

The portion of the drain fitting which laps the outlet opening 2provides a seat for a strainer 9.

The invention claimed is:

1. A drain fitting for the outlet 03 a receptacle comprising an annularbody fitted fiush against the receptacle around the outlet opening andhaving an outwardly projecting peripheral flange, a weld between theouter periphery of the fiange and the receptacle, said body having aportion lapping the outlet opening and providing a strainer seat, saidbody also having an annular groove underlying the margin of the outletopening, and means in the groove for sealing the interstice between themargin of the outlet opening and the body of the drain fitting.

2. A drain fitting "for the outlet of an all metal shower stallcomprising a ring-like body fitted flush against the shower stall aroundthe outlet opening thereof, an endless weld uniting the entire outerperiphery of the body and the shower stall, said body having a portionlapping the outlet opening and adapted to provide a strainer support,and an endless weld unitin the entire margin of the outlet opening andthe entire adjacent circumt'erential portion of the ring-like bodyinwardly of the strainer support.

3. A drain fitting for the outlet of an all metal shower stallcomprising a ring-like body fitted flush against the shower stall aroundthe outlet opening thereof, an endless weld uniting the entire outerperiphery of the body and the shower stall, said body having an endlessgroove therein located immediately adjacent to and para leling themargin of the outlet opening, and an endless weld uniting the entiremargin of the outlet open ing and the wall of the groove.

In witness whereof, I hereto afiiX my signature.
